Alright so I've been running the cyan nightlies, I just updated to the latest one, installed the battery fix. Everythings working fine, put my phone down for and hour and the batt is at like %75, I go under battery use and it puts the screen at 79%, is this normal? I had my screen off most of the time and when it was on it wasnt bright and if this isn't normal how can I fix it?
Have you rebooted to see if it does this after every reboot? Try rebooting normally then see if its still doing it.
If so, then reboot into recovery, wipe dalvik, then reboot normally. Check your battery stats again after a couple hours and see if it's still doing it after the dalvik wipe.
(FYI, this belongs in Q&A section)
can you link to the battery fix plz?
I have had very high display usage on every version of CM6, and you will find it is a VERY common complaint on CDMA Hero's running CM6.
Everyone says it's because Froyo is more efficient, and uses less battery overall, so your display percentage is higher.
I call B.S. on that. I have had poor battery life with the more than 20 nightly versions I have run. I have had the Hero since the day before it came out, and I have never had worse battery life. I even bought a new battery thinking my battery was dying on me, and I still won't make it through a day (7 am - 11 pm) without plugging the phone in during the day.
My guess is there is something up with the display/lights/light sensor drivers that have been implemented in CM6 that don't allow something with the display to sleep properly. Either that, or the battery usage screen is simply completely inaccurate.
I could literally reboot my phone, leave it untouched with the screen off for four hours, then turn on the screen for one minute, and the display usage would shoot up to 50-75%. There is no way one minute of screen usage is using more battery than 4 hours of phone standby using the radio, checking email/twitter/facebook/gmail.
Anyway, that's just my opinion on the matter. Other than the battery life, the newest nightlies of CM6 are simply incredible, so I just deal with the poor battery life.
@ziggy682 -- Thanks for that info. I haven't yet tried CM6 (mainly cuz I'm so dependent on some Sense apps and widgets), and now that I'm reading about some battery issues I may hold off on trying it even longer.
@omair2005 -- if you haven't found it yet, here's the new thread on collin_ph's battery tweak specifically for CM/darch ROMs: http://forum.xda-developers.com/showthread.php?t=762283
I have not yet updated my Captivate to 2.2. Reading posts in regard to the update I am very bothered by a common complaint that battery life has just died. My Captivate has excellent battery life using it fairly heavily over a 1 day period. I charge it every nite. Also, my GPS is workng fine in 2.1. So am considering not updating it due to the problems I am hearing about.
Anyone else have input on battery life after the update??
I went from STOCK 2.1 to Cognition 4.1 (built on Froyo 2.2) and my battery life is about the same. My usage varies wildly from day to day, but as best as I can tell, overall battery consumption is about equal.
I wonder if the people complaining about battery life have set up their phone "post-update" with different apps or turned on "apps syncing background data"...
Battery life did reduce on 2.2 but it is obvious in my point of view. But its not too bad either.
it's about the same, i upgraded to stock 2.2, feel no difference on the battery life. moderate usage last mine for about more than 24 hrs, u should update to froyo for you to experience it.

I upgraded Stock 2.2 end of Feb and noticed a big drop in my battery life the first week. But just reading above, i did turn on "apps syncing background data" so i think that's my problem. Just turned that off so we shall see...
Let your phone go through a week or so recharging cycle before judging its battery life after a ROM flashing. You just lost all your battery stats when flash a new ROM. Your phone/OS has no clue how your battery will operate until it has time to learn or you manually calibrate it.
For what it is worth, my battery life is about the same or slightly better than leaked 2.2 ROM as well as 2.1 ROM. No big changes.
My battery has been about the same since the 2.2 upgrade. At first it felt like my battery was draining quicker but I also noticed I was playing with more phone more. The screen is the biggest power drain on the phone so just playing with menus and looking at new settings can cause a small dent.
Give it a week or two after upgrading and you'll notice it'll be about the same. Unless of course you have more accounts or programs syncing data in the background.
Why upgrade to 2.2
Thanks everyone for the input. The more I read and hear the more I am leaning toward not upgrading to 2.2. On different forums I am seeing and hearing problems with battery life and some saying about the same battery life. Also, seeing GPS not being fixed or going from working ok or good to not working so good. Right now my phone does everything I want, GPS works really good, email works fine, internet works fine, battery life is outstanding, mp3 works great, screens all are clean and to my liking, I have an easy work around for turning off 3G and one tap returning my volumes to normal after using a USSD code.
REally cannot see any advantage to upgrading and risking introducing a problem I don't need. The list of new features really does not thrill me.

2.2 ROM is a big step forward, not backward, IMO. Sure it didn't solve GPS issue but it is not making it worse either. GPS issue is purely hardware issue. If you have a good one, it doesn't matter which stock firmware you use.
I just can't see any disadvantage for upgrading (other than slightly more difficult to root or unlock, but not impossible). Battery life thing is as I mentioned above. You will see all kinds of complaints (either dain too fast or too slow) after a new firmware comes out, any firmware. You don't know what you're missing until you upgraded.
I noticed a big improvement in battery life. Sometimes with light use it will last up to four days, whereas before with 2.1 it would putter out after maybe two days.
GPS isn't fixed, but drop one of many GPS fixes in and it will get somewhat normal performance.
Wifi sleep policy
You may also want to check the Wifi sleep policy after the upgrade to Froyo. In my case, the default was "Never sleep". Changing this to "When screen turns off" improves battery life on 2.2, as it does on 2.1.
Just my $.02 worth.

I'm on stock 2.2 since the day it came out. My battery life is actually trending worse day-by-day. I did a full battery clear/reset this weekend and after 4 days I'm finding battery life is not improving at all. The degradation from stock 2.1 is significantly noticeable to me.
For the first couple of days post-update it seemed actually to be better, but got worse and worse, to where I was lucky to find the phone working 12 hours after disconnecting from the charger @ 100% ... even if I hadn't -touched- the phone during the day. My applications loaded are virtually identical to before.
I did have Background Data on, so I've just disabled it, but was this option not in 2.1? I know that Google Voice, etc, were doing background syncs in 2.1.
It can't be WiFi, as for the last 2-3 days I've kept WiFi turned off. However just for sanity I did adjust the sleep policy.
I'm wondering ... my battery woes seemed to start when I hooked up my Microcell. Could having a strong 3G signal so close to the phone actually be causing problems?

That might be your problem. I don't know. I know 2.1 doesn't work very well with microcell either.
Yep. I'm pretty convinced it is the microcell now. Phone works great with it from a call/data/signal standpoint. However after unplugging my microcell last night, charging my phone to 100%, and then letting the phone discharge normally with no microcell ... I'm now 10 hours later and have an almost full battery.
Sad, because our reception here is so spotty that we lose calls and data regularly without the microcell. My wife says her phone charge has been pretty normal, so I'm getting ready to move the cell away from my desk and see if distance helps the story.
So, as far as this thread is concerned, my results for 2.2 and battery life are great ... better than with 2.1 ... just don't use it with a microcell.
Froyao 2.2 Battery Usage Dillema
I see no significant or excess battery drain while riding the KB1 over the JF6.
Just a thought for those experiencing excessive or significant battery drain. KB1 loads some new features and new additional bloatware that loads on boot and runs as a service, process and both.
If you're familiar with poking around your system settings and understand what doesn't need to always be running in the background, or what doesn't need to load on boot, you can simply kill the process and even alter the way a certain application handles on boot.
By killing many unneeded or unwanted processes at boot time, it will significantly save you hours upon hours of battery life in the longer scheme.
Another FYI, Lithium Ion batteries have memory. You need to train or retrain the batteries memory over time in order to sustain a longer life for it.
Tips:
Don't continually through the charger on your device after minimal drainage. Let the battery run down before fully recharging it again.
When flashing to another ROM wipe your battery stats.
When flashing any new code to your device - a few forced charge deaths to purge the battery and reset the memory again prior to recharging may be a good idea...
Hope this helps...

Ok...this is going to sound completely outrageous! It seems outrageous to me even I have never had this good of battery consumption ever! The phone was purchased 16/08/10 and has retained the standard battery all this time and had various Samsung ROMs on it. Mostly DarkyROMs that have improved battery quite considerably. It currently has its first stable ROM of ICS since I started flashing ICS from just prior to RC1. The ROM is a bit of a mix-matched frankenstein build of a ROM by me originated from MyICS and OneCosmis RC3.1. I have recently experienced allot of issues (including very poor battery drain) prior to this last flash and so have many of my users...actually most jumping **** (and I don't blame them).
My last ROM flash seemed to stable and go through perfectly, I was running with my own 2.0.1 and was about to release this ROM (that I'm currently on from a system dump) as a 2.2.0 version update for everyone else.....however I have held back because of the announcement of RC4.....so any of the improvements I haven't released. The install procedure backs up battery stats so as not to need re-calibration and has done so for the last 3 or 4 install. I am running the latest platypus kernel made for RC4 though
Anyway the last time I had my phone on any decent charge 22hours ago. It's currently 10.40pm EST and phone went on charge about 12.30pm lastnight. Since then I have had data left on (something I wouldn't normally do...I was used to renaming APN prior to ICS) and wifi on* (granted I have latest Juice defender ultimate)
*set to trained locations to auto-on within 250m of known wifi access point and disable 3G when wifi connected
I have gone the whole day today, with a small amount of internet (damn genie widget gets me every time with cool interesting things flashing up on the screen lol) and moderate phone usage; texting and a hand full of 10-15min phone calls....nothing out of the ordinary.
I plugged the phone to USB to transfer some things from work and it was plugged in for approximately 15-20seconds. I use multi-mount SD card app (I have included the lite version in my ROM) and allows for fast transactions and also to be able to use the phone whilst connected etc (read up about it). And I did the same here at home to transfer the things off again. It has remained sitting beside my PC untouched (unusual cause I like to fiddle) for the last 3 hours...and decided to pick it up and glaced at the battery 90%. Ok so I waited another hour and glanced again and STILL 90%.
Is there something weird going on here that I should know about? My phone has never been this good even if I left it completely on standby and in flight mode it would have eaten more than that! It seems almost stupidly impossible.
Fill me in on your take of this situation? Happy to do a complete system dump to try figure this sh!t out cause I made so many mods last ROM update I wouldn't know which one is contributing or if all or none?
edit: included more information
It's now 2:20am I am going to bed. My phone is 86%
A drop of only 4% in nearly 4hours. 1% per hour is not too bad
How do you handle synchronization, and why kind of tweaks do you perform with juicedefender?
heh i know what you mean
Im using as well icssgs rc4 (pulled) for 3 days, and right now i have 10% left after 29 hours of using my phone as wifi, downloading, sync, calls, sms and some music, all i can say is that rc4 +platypus kernel is the beast for the battery. my phone never lasted for such a long time, even on rc3.1 it used to die after 18 hours of being idle.
Reporting
7am 77%
10am 62%
10.55am - poor signal and market prompted to download an update for LinkedIn battery has plumited to 23%
36hours use and still 23% battery is pretty good. At least the resil
I will be making a deodexed version of RC4 sometime soon with a few extra bonuses ....however it won't be all that special as I have been giving away my secrets everywhere on the forum to help others on any ROM (not just my own) so anything included in my next release will be old news lol
Juice defender? Tweaks? I am not sure what you mean? You mean what are my settings?
Ok...wtf? Battery is climbing back up again now? That is something that has never happened before! Im on 26% again
realy ? ))
Offfical time of death 4.34pm EST. approximately 40hours after full charge. I am stoked with that.
Edit: I will be making a donation to Platypus Kernel right now
Can you tell which rom you had before flashing rc4 and another question are you experiencing any other problems with the rom like sd problems because im considering to go rc4 too.

I am still running RC3.1, I am just using the RC4 kernel
I am in the process of developing my own RC4 ROM based off this RC3.1 (my own version of it anyway) that is the first ROM I have that is stable. All versions of my ROMs prior to this have been very unstable. ROM is still odexed so that will be my first point of call and then repackage and get it up and running.
I am in the process of compiling some java code for wifi calling on vibrant though so I am too busy to even start on my ROM
7 hours off fully charged battery since the upgrade completed, and down to 10%. Anyone else with battery life issues since receiving the OTA?
edit: phone temperature also runs very hot now since the update-- Gingerbread was quite a bit cooler to run.
I briefly ran the 217 OTA build before installing safestrap and rolling to a Cyanogenmod image.
I noticed that my phone was MUCH hotter than it had been while running the older GB-based rom -- however, I can't comment on the battery life itself.

I've been running .217 leak for a few weeks, and found that if you have a lot of MP3s on an SDcard, the phone will run really hot while it builds the MP3 database.

It does indeed run much hotter with the screen on. Are you experiencing heat issues with Cyanogenmod, or was it only under the 217 OTA?

Was it a one-time or some-time thing, or was the phone constantly hot? Did you remove any of the files, or was there a workaround to prevent building the database?
It's been stated that initially expect very poor battery life immediately after upgrading to ICS and I would expect heat to be another factor as the CPU is in constant use updating all the new databases, sync'ing etc...that is going on.
(stated in the Motorola soak test forums to expect this).

+1 its expected. I always try to give new roms/updates at least 3 or 4 days to smooth itself out. Especially when upgrading from cupcake to froyo to gingerbread to ics.......

Yeah it should be better after a couple of three days. I can get 14-16 hours on network and 25-30 hours when on steady wifi.

It ran quite hot in the 217 OTA itself. Once I flashed over to cyanogenmod, it got cooler and has been running at roughly the same temperature as when i ran the GB rom.
I have very few MP3's on the SD card. It's actually the card from my old D1 and mostly has nandroid and titanium backup data on it
Odd, I haven't noticed any increase in heat, battery life is still good for me.
Upgraded OTA on monday, so 2 days now. I have a 32gig sd card, and the internal sdcard and the 32gig are loaded full of mp3's, a few videos, and titanium backups.
I want to say battery life is better than normal. But I believe this is only due to fixing a few issues over the weekend with misbehaving apps.

Alright, it's been four days and battery life still sucks-- the phone is now only charging to 60% capacity, and phone spontaneously reboots, runs hot and apps still crash... and then I read that V217 OTA is halted due to "software issues"-- what recourse do I have? I don't pay "insurance" (which works out to the price of a new phone in 2 years). Will VZW address or swap the phone given that this power issue and phone instability was due to software upgrade they prompted on the phone?
Strange... Powered off the Droid 4 before bed and plugged into charger. Woke up and it was at 100%. Powered on, rebooted into safestrap/cwm and wiped cache, Dalvik, and battery stats. Rebooted and left it on charger, in case of quick drain again.
Will see if wife still experiences issues during her day. If so then this is most likely software or OS issue and after I get home from work I'll have to try backup and FXZ to see if a clean OS and gradual install of apps / restore some old data resolves the issue.
Step 1 is hunting down D4 FXZ threads on XDA and checking what's involved.

I've been finding that the battery life and heat has improved for me since installing the OTA. I came from stock, rooted, Gingerbread 219. For the past month or so, I had been noticing that my phone was getting very hot just by charging it (could be due to some app that I couldn't narrow down), but that stopped after the ICS OTA.
Additionally, after the last GB OTA, I noticed that the keyboard lighting would shut off even in complete darkness. That also seems to be fixed with the ICS OTA.

I've had a couple of interesting issues since I updated this morning. First, my media files on my microSD card "disappeared" in that My Gallery no longer displayed pix and vids on the microSD card and Winamp couldn't find any of my MP3s. A reformat of the card seems to have fixed it, for now.
The other issue is that the battery seemed to drain much more quickly than it did when I had Gingerbread. I hope what was said here about that being the case for about the first day or so is true. I would hate to think that this is the nature of ICS.
Didn't do the FXZ / destructive reinstall yet; was doing some more investigation last night-- phone was draining about battery 10% every 10 minutes. The only two things showing under Settings-->Battery were Screen at 60% and Media com.motorola.android.omadrm at 40%. Rebooted, set to charge before bed and now this morning I see other items listed under battery: Android System, Android OS, Mail. Phone is now at 80% battery running on battery for the last 30 minutes. When the screen goes off and I turn it back on, I sometimes see "Battery Extender" flash in the status bar.
Did an
Code:
adb reboot bootloader
to get to the bootloader. Then did a
Code:
fastboot devices
and saw that the phone was listed. Launched RSDLite and flashed the fxz xml.zip file and all seemed well...
phone started up, there was a little android icon with gears spinning inside of it and a progress bar crossing. phone rebooted again, "optimized" android applications, and finally came back to the same system as before-- nothing got wiped. I guess I'll have to do a Settings/Privacy/Factory Reset to get an actual wipe.
Rather than doing a wipe, debating setting up safestrap, going to the safe partition and installing an alternate ICS ROM.
Before going that route at all, there are 27GB of about 7000 mp3 files on the external SD. I'm going to pull the external SD and see how battery life is first.
No battery benefit after pulling out the external SD card; still about 10% battery drain every 10-15 mins.
Did the Settings/Privacy/Factory reset-- currently at 30% drain in 120 minutes. Seems improved, but this is also without the external SD in the device.
Saw a few different things in forums, including searching through some of the alternate ROMs for D4 and looking at some of the Razr ICS upgrade battery issue complaints:
--some said they were having battery issues until doing factory wipe and then reinstalling apps from Play Store without restoring old data
--some said there was something stuck on their external sd that required a full re-format and then restoring data back to the external sd which returned battery life to "normal"
--others said that media indexing is taking place and to give it a few days (seriously? is there no way to disable this or uninstall whichever application is doing this??? the wife said she wouldn't mind scrolling through folders rather than having fully indexed media by artist/album/genre)-- And she raises the valid point, "It used to work fine before!" What changed between Ginger Bread and Ice Cream Sandwich to require this much indexing and what's the fix for it given that people can't return back to GB? Which QA engineer at Verizon/GoogleRola thought it would be a good idea to release an update with this massive issue? Is the intent to discourage people from listening to their locally stored music and to have them rely on data plan intensive "cloud services"? Is there some application that can do the indexing on a more powerful machine like a PC and then upload the indices / export databases to the phone?
140 minutes at 60%-- still at full factory resetted stock from this morning, no external SD card in phone, no media on internal SD card.
I suppose Plan B is to call Verizon and tell them that the battery life is complete crap since their update and to request a CLN-- hoping that it's not running ICS.
to clarify: no apps have been restored / reinstalled-- what on earth could possibly be digesting battery like this?
edit: saw someone's post suggesting settings/more.../mobile networks/network mode - preferred network = LTE/CDMA instead of Global. Giving that a shot.
Not sure what did the trick, but after observing 4 hours at 60%, and Disabling a bunch of the bloatware, re-added the external memory card (with all gazillion mp3s on it) and began installing previously used software. A charge later and a few reboots after, was getting 4 more hours with battery at 90%. No idea what did the trick as I ran through too many variables and never reset them to be able to isolate one specific one.
Good luck to anybody else that may experience this issue in the future.
Thanks for the report. I too did the factory reset and reformatted my card. I think I've had a tiny bit of improvement, but still go down to about 60% capacity after two hours away from the charger with moderate use (Facebook, Twitter, Tapatalk, etc., no streaming or media play). I have my display set to auto, have changed the radio to CDMA/LTE only and have disabled as much bloatware as I can. I'm now trying the battery training FoxKat recommends to see if that will help.
i installed android 7 on a nook hd (7") and ran it for about 2.5 months. As soon as I installed it I could feel the battery area was warm to very warm. It continued to be like that for the 2 and a half months I had it on there.
With android 7, I would get about a day of use off a full charge. I could watch the battery % drop as soon as it was unplugged from the charger. I kept the wireless off and airplane mode enabled most of the time to try to get more life. I could get about 2 hours if surfing the web on wifi.
finally it started jumping the brightness to 100% and wouldn't let me adjust it downward (only happened on certain web pages - still worked fine for reading books, but I had to reboot and reset the brightness every time.
I uninstalled android 7 and went back to stock nook 2.2.1 and my problems vanished. Battery life is back, it took me about 2 hrs to download and reinstall 2.2.1 and I had the nook on and wireless enabled the whole time and the battery never got hot and battery is still at 97%. With android 7 I'd be in 60's by now if not 40's.
I liked being able to install Brave browser and a couple apps, but I hated the android 7 keyboard, and the whole thing was sluggish, so I'd wind up tapping and retapping and getting 2 or 3 extra tabs opened that I didn't really want...
I'm gonna run stock for a week or so and make sure everything is fine and then try CM11 and see if will run better.
I really like the nook for reading books I've got a Kindle oasis and I like the nook better. and the 9" hd+ is great for reading .pdf manuals while working on things without having to have a laptop around.
only wish there was a way to strip the google out of the Nook. android isn't an operating system, its a retailing app...
anybody got a version of android they like that isn't so hard on the battery and not so sluggish???
